The measured PCBs and OCPs were grouped as sum PCB and sum OCPs.
The measured PCBs and OCPs concentrations were lipid adjusted and grouped as sum-PCBs and sum-OCPs (μg/kg lipid).
The values received are statistically indistinguishable from random values with the same sum, but completely independent of the group sums.
To determine the optimal number of clusters, within-group sums of squares were calculated for partitions involving between 1 and 9 clusters [63], [65].
For each of the simulated values, the PDANOVA package of PDAP (Garland Jr et al., 1993) was used to compute within- and between-group sums of squares, mean squares, and corresponding F ratios, as in conventional ANOVA.
We recorded data on cIMT measurements, age, BMI, and lipid metabolism parameter trends across increasing quintiles of cholesterol, lathosterol, campesterol, and sitosterol using one-way analysis of variance (ANOVA) and partitioning the between-group sums of squares into trend components.
Like conventional analyses of variances, the perMANOVA calculates an F statistic by taking the ratio of among group sums of squares to within group sums of squares.
In this study, a score of 3 (area under the curve, 0.610; 95% confidence interval (CI), 0.514 0.706; sensitivity, 63.4%; specificity, 60.1%) was determined as the cutoff score for separating the MRP2-positive group (sums between 3 and 6) from the MRP2-negative group (sums between 0 and 2).
"If we live in the country, if we live an active life, we won't need wheelchairs," said Jill Myers, 62, one of the group, summing up its determined optimism.
Khuensai Jaiyen, an editor of an organization that reports news about one of the largest of the country's many minority groups, summed up the relative good feelings about the president, who later commanded troops in his region.
Between-groups sum of squares.
